TECHNICAL FIELD OF THE INVENTION

This invention is related to an apparatus for computer control in one aspect, it relates to an apparatus for automatically connecting a nearby wireless device to a remote location on a computer network.

BACKGROUND OF THE INVENTION

Global communication networks such as the Internet provide businesses with a new infrastructure for reaching millions of potential customers. So-called “web pages” have become a major vehicle for providing information content (e.g., advertising) to users, and a convenient method for distributing information the users from remote locations on the network.

The emergence of e-commerce over the Internet, and the resulting scramble to capture the attention of users now demands more effective ways for vendors to direct their advertising to potential customers. Such efforts are complicated by the development of so-called wireless devices, e.g., mobile computers and other digital computing devices which are connected to the Internet by means of a radio frequency interface. These wireless devices are frequently employed while the user is actually moving e.g., walking or traveling in an automobile, train, airplane, etc. Thus, new methods and apparatus are needed to facilitate connection of wireless devices to desired locations on the Internet.

It is known to connect a wireless device to a remote location on a network by manually inputting a network address. However, in many cases the address of a remote location is unknown or unavailable to the user. In other cases, the network address is available (e.g., displayed in advertising), but it is cumbersome or even unsafe (e.g., while driving a car) for the user to enter the desired address using the tiny buttons or stylus often associated with a wireless device. A need therefore exists, for a system for connecting a wireless device to a remote location on a network which does not require the user to manually input a network address.

In many cases, an advertiser desires to provide the user of a wireless device with information or knowledge which is especially relevant to the user's current geographic location, e.g., nearby restaurants or shopping opportunities. Further, unless the user of a wireless device has a GPS or other positioning system available, the user typically does not know precisely what his or her current geographic location is. A need therefore exists, for a system for connecting a wireless device to a remote location on a network which is associated with the current geographic location of the wireless device, without requiring the wireless device or its user to provide any geographic location information.

SUMMARY OF INVENTION

The present invention disclosed and claimed herein comprises, in one aspect thereof, a system for connecting a wireless device to a remote location on a computer network. The wireless device includes a processor and a transmitter/receiver for sending and receiving radio frequency signals to provide two-way digital communication between the processor and the computer network. The system comprises a beacon unit and a beacon signal receiver circuit. The beacon unit is disposed at a location and includes a transmitter which transmits a beacon signal into a target region adjacent to the location The beacon signal receiver circuit is disposed with the wireless device and adapted to receive the beacon signal when the wireless device is within the target region. The beacon signal receiver circuit is operably connected to the processor of the wireless device. In response to receiving the beacon signal, the beacon signal receiver circuit sends control control signals, the wireless device is connected to a remote location on the computer network.

DESCRIPTION OF THE INVENTION

Referring now toFIG. 1, there is illustrated a block diagram of a system for controlling a personal computer (“PC”)112 via an audio tone transmitted over a wireless system utilizing a TV. In the embodiment illustrated inFIG. 1, there is provided atransmission station101 and a receivestation117 that are connected via acommunication link108. Thetransmission station101 is comprised of atelevision program source104, which is operable to generate a program in the form of a broadcast signal comprised of video and audio. This is transmitted via conventional techniques along channels in the appropriate frequencies. The program source is input to amixing device106, which mixing device is operable to mix in an audio signal. This audio signal is derived from anaudio source100 which comprises a coded audio signal which is then modulated onto a carrier which is combined with thetelevision program source104. This signal combining can be done at the audio level, or it can even be done at the RF level in the form of a different carrier. However, the preferred method is to merely sum the audio signal from themodulator102 into the audio channel of the program that is generated by thetelevision program source104. The output thereof is provided from themixing device106 in the form of broadcast signal to anantenna107, which transmits the information over thecommunication link108 to anantenna109 on the receive side.

On the receive side of the system, aconventional receiver110, such as a television is provided. This television provides a speaker output which provides the user with an audible signal. This is typically associated with the program. However, thereceiver110 in the disclosed embodiment, also provides an audio output jack, this being the type RCA jack. This jack is utilized to provide an audio output signal on aline113 which is represented by anaudio signal111. Thisline113 provides all of the audio that is received over thecommunication link108 to thePC112 in the audio input port on thePC112. However, it should be understood that, although a direct connection is illustrated from thereceiver110 to thePC112, there actually could be a microphone pickup at thePC112 which could pick the audio signal up. In the disclosed embodiment, the audio signal generated by the advertiserdata input device100 is audible to the human ear and, therefore, can be heard by the user. Therefore, no special filters are needed to provide this audio to thePC112.

ThePC112 is operable to run programs thereon which typically are stored in aprogram file area116. These programs can be any type of programs such as word processing programs, application programs, etc. In the disclosed embodiment, the program that is utilized in the system is what is referred to as a “browser.” ThePC112 runs a browser program into facilitate the access of information on the network, for example, a global communication network known as the “Internet” or the World-Wide-Web (“Web”). The browser is a hypertext-linked application used for accessing information. Hypertext is a term used to describe a particular organization of information within a data processing system, and its presentation to a user. It exploits the computer's ability to link together information from a wide variety of sources to provide the user with the ability to explore a particular topic. The traditional style of presentation used in books employs an organization of the information which is imposed upon it by limitations of the medium, namely fixed sized, sequential paper pages. Hypertext systems, however, use a large number of units of text or other types of data such as image information, graphical information, video information, or sound information, which can vary in size. A collection of such units of information is termed a hypertext document, or where the hypertext documents employ information other than text, hypermedia documents. Multimedia communications may use the Hypertext Transfer Protocol (“HTTP”), and files or formatted data may use the Hypertext Markup Language (“HTML”). This formatting language provides for a mingling of text, graphics, sound, video, and hypertext links by “tagging” a text document using HTML. Data encoded using HTML is often referred to as an “HTML document,” an “HTML page,” or a “home page.” These documents and other Internet resources may be accessed across the network by means of a network addressing scheme which uses a locator referred to as a Uniform Resource Locator (“URL”), for example, “http://www.digital.com.”

The Internet is one of the most utilized networks for interconnecting distributed computer systems and allows users of these computer systems to exchange data all over the world. Connected to the Internet are many private networks, for example, corporate or commercial networks. Standard protocols, such as the Transport Control Protocol (“TCP”) and the Internet Protocol (“IP”) provide a convenient method for communicating across these diverse networks. These protocols dictate how data are formatted and communicated. As a characteristic of the Internet, the protocols are layered in an IP stack. At higher levels of the IP stack, such as the application layer (where HTTP is employed), the user information is more readily visible, while at lower levels, such as the network level (where TCP/IP are used), the data can merely be observed as packets or a stream of rapidly moving digital signals. Superimposed on the Internet is a standard protocol interface for accessing Web resources, such as servers, files, Web pages, mail messages, and the like. One way that Web resources can be accessed is by browsers made by Netscape® and Microsoft Internet Explorer®.

Referring again now toFIG. 1, the user can load this program with the appropriate keystrokes such that a browser window will be displayed on adisplay118. In one embodiment, the user can run the browser program on thePC112 such that the browser window is displayed on thedisplay118. While watching a preferred program, the user can also viewdisplay118. When an audio signal is received by thereceiver110 and the encoded information is contained therein that was input thereto by the advertiser, thePC112 will then perform a number of operations. The first operation, according to the disclosed embodiment, is to extract the audio information within the received audio signal in the form of digital data, and then transmit this digital data to a defined location on the global communication network via amodem connection114. This connection will be described hereinbelow. This information will be relayed to a proprietary location and the instructions sent back to thePC112 as to the location of the advertiser associated with the code, and thePC112 will then effect a communication link to that location such that the user can view on thedisplay118 information that the advertiser, by the fact of putting the tone onto the broadcast channel, desires the viewer to view. This information can be in the form of interactive programs, data files, etc. In one example, when an advertisement appears on the television, the tone can be generated and then additional data displayed on thedisplay118. Additionally, a streaming video program could be played on the PC received over the network, which streaming video program is actually longer than the advertising segment on the broadcast. Another example would be a sports game that would broadcast the tone in order to allow a user access to information that is not available over the broadcast network, such as additional statistics associated with the sports program, etc.

By utilizing the system described herein with respect to the disclosed embodiment ofFIG. 1, an advertiser is allowed the ability to control a user'sPC112 through the use of tones embedded within a program audio signal. As will described hereinbelow, the disclosed embodiment utilizes particular routing information stored in thePC112 which allows the encoded information in the received audio signal to route this information to a desired location on the network, and then allow other routing information to be returned to thePC112 for control thereof to route thePC112 to the appropriate location associated with that code.

Referring now toFIG. 2, there is illustrated acomputer204, similar tocomputer112, connected to display information ondisplay118. Thecomputer204 comprises an internal audio or “sound”card206 for receiving the transmitted audio signal through receiveantenna109 andreceiver110. Thesound card206 typically contains analog-to-digital circuitry for converting the analog audio signal into a digital signal. The digital signal may then be more easily manipulated by software programs. Thereceiver110 separates the audio signal from the video signal. A special trigger signal located within the transmitted advertiser audio signal triggers proprietary software running on thecomputer204 which launches a communication application, in this particular embodiment, the web browser application located on thePC204. Coded advertiser information contained within the audio signal is then extracted and appended with the address of a proprietary server located on the communication network.

The remote server address is in the form of a URL. This appended data, in addition to other control codes, is inserted directly into the web browser application for automatic routing to the communication network. The web browser running onPC204, and communicating to the network with aninternal modem208, in this embodiment, transmits the advertiser information to the remote server. The remote server cross-references the advertiser product information to the address of the advertiser server located on the network. The address of the advertiser server is routed back through thePC204 web browser to the advertiser server. The advertiser product information is returned toPC204 to be presented to the viewer ondisplay118. In this particular embodiment, the particular advertiser product information displayed is contained within the advertiser'sweb page212. As mentioned above, the audio signal is audible to the human ear. Therefore the audio signal, as emitted from the TV speakers, may be input to thesound card206 via a microphone. Furthermore, the audio signal need not beta real-time broadcast, but may be on video tapes, CDS, DVD, or other media which may be displayed at a later date. With the imminent implementation of high definition digital television, the audio signal output from the TV may also be digital. Therefore, direct input into a sound card for A/D purposes may not be necessary, but alternative interfacing techniques to accommodate digital-to-digital signal formats would apply.

Referring now toFIG. 3, there is illustrated asource PC302, similar toPCS204 and112, connected to a global communication network (“GCN”)306 through aninterface304. In this embodiment, theaudio signal111 is received byPC302 through itssound card206. Theaudio signal111 comprises a trigger signal which triggers proprietary software into launching a web browser application residing on thePC302. Theaudio signal111 also comprises advertiser product information which is extracted and appended with URL information of an Advertiser Reference Server (“ARS”)308. TheARS308 is a system disposed on theGCN306 that is defined as the location to which data in theaudio signal111 is to be routed. As such, data in theaudio signal111 will always be routed to theARS308, since a URL is unique on theGCN306. Connected to theARS308 is adatabase310 of product codes and associated manufacturer URLs. Thedatabase310 undergoes a continual update process which is transparent to the user. As companies sign-on, i.e., subscribe, to this technology, manufacturer and product information is added to thedatabase310 without interrupting operation of thesource PC302 with frequent updates. When the advertiser server address URL is obtained from theARS database310, it and the request for the particular advertiser product information are automatically routed back through the web browser onPC302, over to the respective advertiser server for retrieval of the advertiser product information to thePC302. Additionally, although the disclosed invention discusses a global communication network, the system is also applicable to LANs, WANs, and peer-to-peer network configurations. It should be noted that the disclosed architecture is not limited to asingle source PC302, but may comprise a plurality of source PCS, e.g.,PC300 andPC303. Moreover, a plurality ofARS308 systems andadvertiser servers312 may be implemented, e.g.,ARS314, and advertiser server. A316, respectively.

The information transactions, in general, which occur between the networked systems of this embodiment, over the communication network, are the following. The web browser running onsource PC302 transmits a message packet to theARS308 over Path “A.” TheARS308 decodes the message packet and performs a cross-reference function with product information extracted from the received message packet to obtain the address of anadvertiser server312. A new message packet is assembled comprising theadvertiser server312 address, and sent back to thesource PC302 over Path “B.” A “handoff” operation is performed whereby thesource PC302 browser simply reroutes the information on to theadvertiser server312 over Path “C,” with the appropriate source and destination address appended. Theadvertiser server312 receives and decodes the message packet. The request-for-advertiser-product-information is extracted and theadvertiser312 retrieves the requested information from its database for transmission back to thesource PC302 over Path “D.” Thesource PC302 then processes the information, i.e., for display to the viewer. The optional Path “E” is discussed hereinbelow. It should be noted that the disclosed methods are not limited to only browser communication applications, but may accommodate, with sufficient modifications by one skilled in the art, other communication applications used to transmit information over the Internet or communication network.

Referring now toFIG. 4a, themessage packet400 sent from thesource PC302 toARS308 via Path “A” comprises several fields. One field comprises the URL of theARS308 which indicates where the message packet is to be sent. Another field comprises the advertiser product code or other information derived from theaudio signal11, and any additional overhead information required for a given transaction. The product code provides a link to the address of theadvertiser server312, located in thedatabase310. Yet another field comprises the network address of thesource PC302. In general, network transmissions are effected in packets of information, each packet providing a destination address, a source address, and data. These packets vary depending upon the network transmission protocol utilized for communication. Although the protocols utilized in the disclosed embodiment are of a conventional protocol suite commonly known as TCP/IP, it should be understood that any protocols providing the similar basic functions can be used, with the primary requirement that a browser can forward the routing information to the desired URL in response to keystrokes being input to a PC. Within the context of this disclosure, “message packet” shall refer to and comprise the destination URL, product information, and source address, even though more than a single packet must be transmitted to effect such a transmission.

Upon receipt of themessage packet400 fromsource PC302,ARS308 processes the information in accordance with instructions embedded in the overhead information. TheARS308 specifically will extract the product code information from the receivedpacket400 and, once extracted, will then decode this product code information. Once decoded, this information is then compared with data contained within theARS advertiser database310 to determine if there is a “hit.” If there is no “hit” indicating a match, then information is returned to the browser indicating such. If there is a “hit,” apacket402 is assembled which comprises the address of thesource PC302, and information instructing thesource PC302 as to how to access, directly in a “handoff” operation, another location on the network, that of anadvertiser server312. This type of construction is relatively conventional with browsers such as Netscape® and Microsoft Internet Explorer® and, rather than displaying information from theARS308, thesource PC302 can then access theadvertiser server312. TheARS308 transmits thepacket402 back tosource PC302 over Path “B.” Referring now toFIG. 4b, themessage packet402 comprises the address of thesource PC302, the URL of theadvertiser server312 embedded within instructional code, and the URL of theARS308.

Upon receipt of themessage packet402 by thesource PC302, themessage packet402 is disassembled to obtain pertinent routing information for assembly of anew message packet404. The web browser running onsource PC302 is now directed to obtain, over Path “C,” the product information relevant to theparticular advertiser server312 location information embedded inmessage packet404. Referring now to FIG.4c, themessage packet404 for this transaction comprises the URL of theadvertiser server312, the request-for-product-information data, and the address of thesource PC302.

Upon receipt of themessage packet404 fromsource PC302,advertiser server312 disassembles themessage packet404 to obtain the request-for-product-information data. Theadvertiser server312 then retrieves the particular product information from its database, and transmits it over Path “D” back to thesource PC302. Referring now toFIG. 4d, themessage packet406 for this particular transaction comprises the address of thesource PC302, the requested information, and the URL of theadvertiser server312.

Optionally, theARS308 may make a direct request for product information over Path “E” toadvertiser server312. In this mode, theARS308 sends information to theadvertiser server312 instructing it to contact thesource PC302. This, however, is unconventional and requires more complex software control. The message packet408 for this transaction is illustrated inFIG. 4e, which comprises the URL of theadvertiser server312, the request-for-product-information data, and the address of thesource PC302. Since product information is not being returned to theARS308, but directly to thesource PC302, the message packet408 requires the return address to be that of thesource PC302. The product information is then passed directly toPC302 over Path “D.”

Referring now toFIG. 5, the method for detecting and obtaining product information is as follows. Indecision block500, a proprietary application running resident on a source computer PC302 (similar to PC204) monitors the audio input for a special trigger signal. Upon detection of the trigger signal, data following the trigger signal is decoded for further processing, infunction block502. Infunction block504, the data is buffered for further manipulation. Indecision block506, a determination is made as to whether the data can be properly authenticated. If not, program flow continues through the “N” signal to function block520 where the data is discarded. Infunction block522, the program then signals for a retransmission of the data. The system then waits for the next trigger signal, indecision block500. If properly authenticated indecision block506, program flow continues through the “Y” signal path where the data is then used to launch the web browser application, as indicated infunction block508. Infunction block510, the web browser receives the URL data, which is then automatically routed through thecomputer modem208 to thenetwork interface304 and ultimately to thenetwork306. Infunction block514, theARS308 responds by returning the URL ofadvertiser server312 to thePC302. Infunction block516, the web browser running on thesource PC302, receives the advertiser URL information from theARS308, and transmits the URL for the product file to theadvertiser server312. Inblock518, theadvertiser server312 responds by sending the product information to thesource PC302 for processing.

The user may obtain the benefits of this architecture by simply downloading the proprietary software over the network. Other methods for obtaining the software are well-known; for example, by CD, diskette, or pre-loaded hard drives.

Referring now toFIG. 6, there is illustrated a flowchart of the process theARS308 may undergo when receiving themessage packet400 from thesource PC302. Indecision block600, theARS308 checks for the receipt of themessage packet400. If amessage packet400 is not received, program flow moves along the “N” path to continue waiting for the message. If the message-packet400 is received, program flow continues along path “Y” for message processing. Upon receipt of themessage packet400, infunction block602, theARS308 decodes themessage packet400. The product code is then extracted independently infunction block604 in preparation for matching the product code with the appropriate advertiser server address located in thedatabase310. Infunction block606, the product code is then used with a lookup table to retrieve theadvertiser server312 URL of the respective product information contained in the audio signal data. Infunction block608, theARS308 then assemblesmessage packet402 for transmission back to thesource PC302.Function block610 indicates the process of sending themessage packet402 back to thesource PC302 over Path “B.”

Referring now toFIG. 7, there is illustrated a flowchart of the interactive processes between thesource PC302 and theadvertiser server312. Infunction block700, thesource PC302 receives themessage packet402 back from theARS308 and begins to decode thepacket402. Infunction block702, the URL of the advertiser product information is extracted from themessage packet402 and saved for insertion into themessage packet404 to theadvertiser server312. Themessage packet404 is then assembled and sent by thesource PC302 over Path “C” to theadvertiser server312, infunction block704. While thesource PC302 waits, infunction block706, theadvertiser server312 receives themessage packet404 from thesource PC302, infunction block708, and disassembles it. The product information location is then extracted from themessage packet404 infunction block710. The particular product information is retrieved from theadvertiser server312 database for transmission back to thesource PC302. Infunction block712, the product information is assembled intomessage packet406 and then transmitted back to thesource PC302 over Path “D.” Returning to thesource PC302 infunction block714, the advertiser product information contained in themessage packet406 received from theadvertiser server312, is then extracted and processed infunction block716.

Referring now toFIG. 8, after receipt of a trigger signal, a web browser application on asource PC302 is automatically launched andcomputer display800 presents abrowser page802. Proprietary software running on thesource PC302 processes the audio signal data after being digitized through thesound card206. The software appropriately prepares the data for insertion directly into the web browser by extracting the product information code and appending keystroke data to this information. First, aURL page804 is opened in response to a Ctrl-O command added by the proprietary software as the first character string.Opening URL page804 automatically positions the cursor in afield806 where additional keystroke data following the Ctrl-O command will be inserted. AfterURL page804 is opened, the hypertext protocol preamble http:// is inserted into thefield806. Next, URL information associated with the location of theARS308 is inserted intofield806. Following theARS308 URL data are the characters /? to allow entry of variables immediately following the /? characters. In this embodiment, the variable following is the product information code received in the audio signal. The product code information also provides the cross-reference information for obtaining the advertiser URL from theARS database310. Next, a carriage return is added to send the URL/product data and close thewindow804. After themessage packet400 is transmitted to theARS308 from thesource PC302, transactions from theARS308, to thesource PC302, to theadvertiser server312, and back to thesource PC302, occur quickly and are transparent to the viewer. At this point, the next information the viewer sees is the product information which was received from theadvertiser server312.

Referring now toFIG. 9, there is illustrated a block diagram of a more simplified embodiment. In this embodiment, avideo source902 is provided which is operable to provide an audio output on anaudio cable901 which provides routing information referred to byreference numeral904. Therouting information904 is basically information contained within the audio signal. This is an encoded or embedded signal. The important aspect of therouting information904 is that it is automatically output in realtime as a function of the broadcast of the video program received over thevideo source902. Therefore, whenever the program is being broadcast in realtime to theuser908, therouting information904 will be output whenever the producer of the video desires it to be produced. It should be understood that thebox902 representing the video source could be any type of media that will result in the routing information being output. This could be a cassette player, a DVD player, an audio cassette, a CD ROM or any such media. It is only important that this is a program that the producer develops which theuser908 watches in a continuous or a streaming manner. Embedded within that program, at a desired point selected by the producer, therouting information904 is output.

The audio information is then routed to aPC906, which is similar to thePC112 inFIG. 1. Auser908 is interfaced with the PC to receive information thereof, thePC906 having associated therewith a display (not shown). ThePC906 is interfaced with anetwork910, similar to thenetwork306 in FIG.3. Thisnetwork910 has multiple nodes thereon, one of which is thePC906, and another of which is represented by anetwork node912 which represents remote information. The object of the present embodiment is to access remote information for display to theuser908 by the act of transmitting from the video program inblock902 therouting information904. Thisrouting information904 is utilized to allow thePC906 which has a network “browser” running thereon to “fetch” the remote information at thenode912 over thenetwork910 for display to theuser908. Thisrouting information904 is in the form of an embedded code within the audio signal, as was described hereinabove.

Referring now toFIG. 10, there is illustrated a more detailed block diagram of the embodiment of FIG.9. In this embodiment, thePC906 is split up into a couple of nodes, afirst PC1002 and asecond PC1004. ThePC1002 resides at the node associated with theuser908, and thePC1004 resides at another node. ThePC1004 represents theARS308 of FIG.3. ThePC1004 has adatabase1006 associated therewith, which is basically theadvertiser database310. Therefore, there are three nodes on thenetwork910 necessary to implement the disclosed embodiment, thePC1002, thePC1004 and theremote information node912. Therouting information904 is utilized by thePC1002 for routing to thePC1004 to determine the location of theremote information node912 on thenetwork910. This is returned to thePC1002 and a connection made directly with theremote information node912 and the information retrieved therefrom to theuser908. Therouting information904 basically constitutes primary routing information.

Referring now toFIG. 11, there is illustrated a diagrammatic view of how the network packet is formed for sending the primary routing information to thePC1004. In general, the primary routing information occupies a single field which primary routing information is then assembled into a data packet with the secondary routing information for transfer to thenetwork910. This is described hereinabove in detail.

Referring now toFIG. 12, there is illustrated an alternate embodiment to that of FIG.9. In this embodiment, thevideo source902 has associated therewith anoptical region1202, whichoptical region1202 has disposed therein an embedded video code. This embedded video code could be relatively complex or as simple as a grid of dark and white regions, each region in the grid able to have a dark color for a logic “1” or a white region for a logic “0.” This will allow a digital value to be disposed within theoptical region1202. Asensor1204 can then be provided for sensing this vide code. In the example above, this would merely require an array of optical detectors, one for each region in the grid to determine whether this is a logic “1” or a logic “0” state. One of the sensed video is then output to thePC906 for processing thereof to determine the information contained therein, which information contained therein constitutes theprimary routing information904. Thereafter, it is processed as described hereinabove with reference to FIG.9.

Referring now toFIG. 13, there is illustrated a block diagram for an embodiment wherein a user's profile can be forwarded to the original subscriber or manufacturer. ThePC906 has associated therewith aprofile database1302, whichprofile database1302 is operable to store a profile of theuser908. This profile is created when the program, after initial installation, requests profile information to be input in order to activate the program. In addition to the profile, there is also a unique ID that is provided to theuser908 in association with the browser program that runs on thePC906. This is stored in a storage location represented by ablock1304. ThisID1304 is accessible by a remote location as a “cookie” which is information that is stored in thePC906 in an accessible location, which accessible location is actually accessible by the remote program running on a, remote-node.

TheARS308, which basically constitutes thePC1004 ofFIG. 10, is operable to have associated therewith aprofile database1308, whichprofile database1308 is operable to store profiles for all of the users. Theprofile database1308 is a combination of the stored inprofile database1302 for all of thePC906 that are attachable to the system. This is to be distinguished from information stored in thedatabase310 of theARS308, the advertiser's database, which contains intermediate destination tables. When the routing information in theprimary routing information904 is forwarded to theARS308 and extracted from the original data packet, the lookup procedure descried hereinabove can then be performed to determines where this information is to be routed. Theprofile database1302 is then utilized for each transaction, wherein each transaction in the form of the routing information received form theprimary routing information904 is compared to the destination tables ofdatabase310 to determine what manufacturer is associated therewith.

The associatedID1304 that is transmitted along with the routing informationprimary routing information904 is then compared with theprofile database1308 to determine if a profile associated therewith is available. This information is stored in atransaction database1310 such that, at a later time, for each routing code received in the form of the information inprimary routing information904, there will associated therewith theIDs1304 of each of thePCS906. The associated profiles indatabase1308, which are stored in association withIDs1304, can then be assembled and transmitted to a subscriber as referenced by asubscriber node1312 on thenetwork910. TheARS308 can do this in two modes, a realtime mode or a non-realtime mode. In a realtime mode, each time aPC906 accesses theadvertiser database310, that user's profile information is uploaded to thesubscriber node1312. At the same time, billing information is generated for thatsubscriber1312 which is stored in abilling database1316. Therefore, theARS308 has the ability to inform thesubscriber1312 of each transaction, bill for those transactions, and also provide to thesubscriber1312 profile information regarding who is accessing the particular product advertisement having associated therewith the routinginformation field904 for a particular routing code as described hereinabove. This information, once assembled, can then be transmitted to thesubscriber1312 and also be reflected in billing information and stored in thebilling information database1316.

Referring now toFIG. 14, there is illustrated a flowchart depicting the operation for storing the profile for the user. The program is initiated in ablock1402 and then proceeds to afunction block1404, wherein the system will prompt for the profile upon initiation of the system. This initiation is a function that is set to activate whenever the user initially loads the software that he or she is provided. The purpose for this is to create, in addition to the setup information, a user profile. Once the user is prompted for this, then the program will flow to adecision block1406 to determine whether the user provides basic or detailed information. This is selectable by the user. If selecting basic, the program will flow to afunction block1408 wherein the user will enter basic information such as name and serial number and possibly ar address. However, to provide some incentive to the user to enter more information, the original prompt infunction block1404 would have offers for such things as coupons, discounts, etc., if the user will enter additional information. If the user selects this option, the program flows from thedecision block1406 to a function block1410. In the function block1410, the user is prompted to enter specific information such as job, income level, general family history, demographic information and more. There can be any amount of information collected in this particular function block.

Once all of the information is collected, in either the basic mode or the more specific mode, the program will then flow to afunction block1412 where this information is stored locally. The program then flows to adecision block1414 to then go on-line to the host or theARS308. In general, the user is prompted to determine whether he or she wants to send this information to the host at the present time or to send it later. If he or she selects the “later” option, the program will flow to afunction block1415 to prompt the user at a later time to send the information. In the disclosed embodiment, the user will not be able to utilize the software until the profile information is sent to the host. Therefore, the user may have to activate this at a later time in order to connect with the host.

If the user has selected the option to upload the profile information to the host, the program will flow to thefunction block1416 to initiate the connect process and then to adecision block1418 to determine if the connection has been made. If not, the program will flow along a “N” path to a time todecision block1420 which will timeout to anerror block1422 or back to the input of theconnect decision block1418. The program, once connected, will then flow along a “Y” path fromdecision block1418 to afunction block1428 to send the profile information with the ID of the computer or user to the host. The ID is basically, as described hereinabove, a “cookie” in the computer which is accessed by the program when transmitting to the host. The program will then flow to afunction block1430 to activate the program such that it, at later time, can operate without requiring all of the setup information. In general, all of the operation of this flowchart is performed with a “wizard” which steps the user through the setup process. Once complete, the program will flow to aDone block1432.

Referring now toFIG. 15, there is illustrated a flowchart depicting the operation of the host when receiving a transaction. The program is initiated at a Start block1502 and then proceeds todecision block1504, wherein it is determined whether the system has received a routing request, i.e., therouting information904 in the form of a tone, etc., embedded in the audio signal, as described hereinabove with respect to FIG.9. The program will loop back around to the input ofdecision block1504 until the routing request has been received. At this time, the program will flow along the “Y” path to afunction block1506 to receive the primary routing information and the user ID. Essentially, this primary routing information is extracted from the audio tone, in addition to the user ID. The program then flows to afunction block1508 to look up the manufacturer URL that corresponds to the received primary routing information and then return the necessary command information to the originatingPC108 in order to allow thatPC108 to connect to the destination associated with the primary routing information. Thereafter, the program will flow to afunction block1510 to update thetransaction database1310 for the current transaction. In general, therouting information904 will be stored as a single field with the associated IDs. Theprofile database1308, as described hereinabove, has associated therewith detailed profiles of each user on the system that has activated their software in association with their ID. Since the ID was sent in association with the routing information, what is stored in thetransaction database1310 is the routing code, in association with all of the IDs transmitted to the system in association with that particular routing code. Once this transaction datable1310 has been updated, as described hereinabove, the transactions can be transferred back to the subscriber atnode312 with the detailed profile information from theprofile database1308.

The profile information can be transmitted back to the subscriber or manufacturer at thenode312 in realtime or non-realtime. Adecision block1512 is provided for this, which determines if the delivery is realtime. If realtime, the program will flow along a “Y” path to afunction block1514 wherein the information will be immediately forwarded to the manufacturer or subscriber. The program will then flow to afunction block1516 wherein the billing for that particular manufacturer or subscriber will be updated in thebilling database1316. The program will then flow into anEnd block1518. If it was non-realtime, the program moves along the “N” path to afunction block1520 wherein it is set for a later delivery and it is accrued in thetransaction database1310. In any event, thetransaction database1310 will accrue all information associated with a particular routing code.

With a realtime transaction, it is possible for a manufacturer to place an advertisement in a magazine or to place a product on a shelf at a particular time. The manufacturer can thereafter monitor the times when either the advertisements are or the products are purchased. Of course, they must be scanned into a computer which will provide some delay. However, the manufacturer can gain a very current view of how a product is moving. For example, if a cola manufacturer were to provide a promotional advertisement on, for example, television, indicating that a new cola was going to be placed on the shelf and that the first 1000 purchasers, for example, scanning their code into the network would receive some benefit, such as a chance to win a trip to some famous resort in Florida or some other incentive, the manufacturer would have a very good idea as to how well the advertisement was received. Further, the advertiser would know where the receptive markets were. If this advertiser, for example, had placed the television advertisement in ten cities and received overwhelming response from one city, but very poor response from another city, he would then have some inclination to believe that either the one poor-response city was not a good market or that the advertising medium he had chosen was very poor. Since the advertiser can obtain a relatively instant response and also content with that response as to the demographics of the responder, very important information can be obtained in a relatively short time.

It should be noted that the disclosed embodiment is not limited to asingle source PC302, but may encompass a large number of source computers connected over a global communication network. Additionally, the embodiment is not limited to asingle ARS308 or asingle advertiser server312, but may include a plurality of ARS and advertiser systems, indicated by the addition ofARS314 andadvertiser server A316, respectively. It should also be noted that this embodiment is not limited only to global communication networks, but also may be used with LAN, WAN, and peer-to-peer configurations.

It should also be noted that the disclosed embodiment is not limited to a personal computer, but is also applicable to, for example, a Network Computer (“NetPC”), a scaled-down version of the PC, or any system which accommodates user interaction and interfaces to information resources. One typical application of the above noted technique is for providing a triggering event during a program, such as a sport event. In a first example, this may be generated by an advertiser. One could imagine that, due to the cost of advertisements in a high profile sports program, there is a desire to utilize this time wisely. If, for example, an advertiser contracted for 15 seconds worth of advertising time, they could insert within their program a tone containing the routing information. This routing information can then be output to the user'sPC302 which will cause the user'sPC302 to, via the network, obtain information from a remote location typically controlled by the advertiser. This could be in the form of an advertisement of a length longer than that contracted for. Further, this could be an interactive type of advertisement. An important aspect to the type of interaction between the actual broadcast program with the embedded routing information and the manufacturer's site is the fact that there is provided information as to the user'sPC302 and a profile of the user themselves. Therefore, an advertiser can actually gain realtime information as to the number of individuals that are watching their particular advertisement and also information as to the background of those individuals, profile information, etc. This can be a very valuable asset to an advertiser.

In another example, the producer of the program, whether it be an on-air program, a program embedded in a video tape, CD-ROM, DVD, or a cassette, can allow the user to automatically access additional information that is not displayed on the screen. For example, in a sporting event, various statistics can be provided to the user from a remote location, merely by the viewer watching the program. When these statistics are provided, the advertiser can be provided with profile information and background information regarding the user. This can be important when, for example, the user may record a sports program. If the manufacturer sees that this program routing code is being output from some device at a time later than the actual broadcast itself, this allows the advertisers to actually see that their program is still being used and also what type of individual is using it. Alternatively, the broadcaster could determine the same and actually bill the advertiser an additional sum for a later broadcast. This is all due to the fact that the routing information automatically, through a PC and a network, will provide an indication to the advertiser the time at which the actual information was broadcast.

The different type of medium that can be utilized with the above embodiment are such things as advertisements, which are discussed hereinabove, contests, games, news programs, education, coupon promotional programs, demonstration media (demos), and photographs, all of which can be broadcast on a private site or a public site. This all will provide the ability to allow realtime interface with the network and the remote location for obtaining the routed information and also allow for realtime billing and accounting.

Referring now toFIG. 16, there is illustrated a general block diagram of a disclosed embodiment. A bar codescanning input device1600 is provided by a input device distributor to customers and is associated with that distributor via a input device ID stored therein. Theinput device1600 is either sold or freely distributed to customers for use with their personal computing systems. Since more and more products are being sold using bar codes, it can be appreciated that a user having theinput device1600 can scan bar codes of a multitude of products in order to obtain more information. Information about these products can be made immediately available to the user from the manufacturer for presentation by the user'scomputer302. Beyond simply displaying information about the product in which the user is interested, the input device distributor may include additional advertising information for display to the user such as information about other promotions or products provided or sold by the input device distributor. Similarly, advertisers may provide catalogs of advertisements or information in newspapers or periodicals where the user simply scans the bar code associated with the advertisement using theinput device1600 to obtain further information. There is provided apaper source1602 having contained thereon anadvertisement1604 and an associatedbar code1606. (Note that the disclosed concept is not limited to scanning ofbar codes1606 frompaper sources1602, but is also operable to scan abar code1606 on the product itself. Also, theinput device1600 can be any type of device that will scan any type of image having information encoded therein.)

After obtaining theinput device1600 from the input device distributor, the user connects theinput device1600 to theirPC302. During a scanning operation,input device1600 readsbar code data1606 and the input device ID into a “wedge”interface1608 for conversion into keyboard data, which keyboard data is passed therefrom into the keyboard input port ofPC302. The importance of the input device ID will be discussed in more detail hereinbelow.

Thewedge interface1608 is simply an interface box containing circuitry that accommodates inputs from both thescanning input device1600 and acomputer keyboard1610. This merely allows the information scanned by theinput device1600 to be input into thePC302. In the disclosed embodiment, thewedge interface1608 will convert any information. The data output from theinput device1600 is passed into thewedge interface1608 for conversion into keyboard data which is readily recognizable by thePC302. Therefore, theinput device1600 is not required to be connected to a separate port on thePC302. This data is recognized as a sequence of keystrokes. However, the output of theinput device1600 can be input in any manner compatible with thePC302. When not receiving scanner data, thewedge interface1608 simply acts as a pass-through device for keyboard data from thekeyboard1610. In any case, the information is ultimately processed by a processor in thePC302 and can be presented to the user on adisplay1612. Thewedge interface1608 is operable to provide a decoding function for thebar code1606 and conversion thereof to keystroke input data.

In operation, the product code of a product is provided in the form of abar code1606. Thisbar code1606 is the “link” to a product. The disclosed embodiment is operable to connect that product information contained in thebar code1606 with a web page of the manufacturer of that product by utilizing thebar code1606 as the product “identifier.” The program operating on thePC302 provides routing information to theARS308 after launching the browser on thePC302 and connecting to theARS308 over theGCN306, whichARS308 then performs the necessary steps to cause the browser to connect to the manufacturer web site, while also providing for an accounting step, as will be described in more detail hereinbelow.

Thebar code1606 by itself is incompatible with any kind of network for the purposes of communication therewith. It is primarily provided for a retail-type setting. Therefore, the information contained in thebar code1606, by itself, does not allow for anything other than identification of a product, assuming that one has adatabase1614 containing information as to a correlation between the product and thebar code1606.

Thewedge interface1608 is operable to decode thebar code1606 to extract the encoded information therein, and append to that decoded bar code information relating to an ID for theinput device1600. This information is then forwarded to theARS308 by the resident program in thePC302. This is facilitated by intermediate routing information stored in the program indicating to which node on theGCN306 the scanned bar code information is to be sent, i.e., to theARS308. It is important to note that the information in thebar code1606 must be converted from its optical image to numerical values which are then ultimately input to the keyboard input port ofPC302 and converted into data compatible with communication software residing on the PC302 (in this case, HTML language for insertion into a browser program). When the scanned information is input to thePC302, the resident program launches the browser program and then assembles a communication packet comprised of the URL of theARS308, the input device ID and the user ID. If another type of communications program were utilized, then it would have to be converted into language compatible with that program. Of course, a user could actually key in the information on thebar code102 and then append the appropriate intermediate routing information thereafter. As will be described hereinbelow, the intermediate routing information appended thereto is the URL of theARS308 disposed on theGCN306.

As part of the configuration for using theinput device1600, thePC302 hosts input device software which is operable to interpret data transmitted from theinput device1600, and to create a message packet having the scanned product information and input device ID, routing information, and a user ID which identifies the user location of theinput device1600. The input device software loads at boot-up of thePC302 and runs in the background. In response to receiving a scannedbar code1606, thewedge interface1608 outputs a keystroke code (e.g., ALT-F10) to bring the input device program into the foreground for interaction by the operating system. The input device program then inserts the necessary information into the browser program. The message packet is then transmitted to interface304 across theglobal communication network306 to theARS308. TheARS308 interrogates the message packet and performs a lookup function using theARS database310. If a match is found between particular parameters of the message packet, a return message packet is sent back to thePC302 for processing.

The input device program running onPC302 functions to partition the browser window displayed to the user into several individual areas. This is for the purpose of preparing to present to the user selected information in each of the individual areas (also called “framing”). The selected information comprises the product information which the user requested by scanning thebar code1606 using theinput device1600, information about the input device distributor which establishes the identity of the company associated with thatparticular input device1600, and at least one or more other frames which may be advertisements related to other products that the input device distributor sells. Note that the advertisements displayed by the input device distributor may be related to the product of interest or totally unrelated. For example, if a user scans thebar code1606 of a soda from Company A, the input device distributor may generate an advertisement of a new soft drink being marketed by Company A, that it sells. On the other hand, the input device distributor may also structure the display of information to the user such that a user requesting product information of a Product X may get the requested information of Product X along with advertisements for a competing item Product Y. Essentially, the input device distributor is free to generate any advertisement to the user in response to the user requesting product information.

The return message packet transmitted from theARS308 to thePC302 is then transmitted back across theGCN306 to theadvertiser server312. Theadvertiser server312 restructures the message packet and appends the particular product information for transmission back to thePC302. Upon receiving the particular advertiser information fromadvertiser server312, thePC302 then retransmits a message to the inputdevice distributor site1616 andE-commerce site1618 to obtain the information that needs to be framed in the browser window displayed to the user.

Therefore, theinput device1600 is associated with the input device distributor by way of a input device ID such that scanning aproduct bar code1606 in order to obtain information about that particular product generates one or more responses from one or more remote sites disposed on theGCN306. Stored in theinput device1600 is the input device ID which establishes its relationship to the input device distributor. Proprietary input device software running on thePC302 operates to decode scanned bar code information and the input device ID received from theinput device1600 andwedge interface1608, and also provides a unique user ID for establishing the location of the user of theinput device1600. The input device software also assembles message packets and works in conjunction with the on-board communication software (e.g., a browser) to automatic ally route the message packets across theGCN306 such that the one or more remote sites disposed on theGCN306 return information to be framed for presentation to the user.

Referring now toFIG. 17, there is illustrated a conversion circuit of the wedge interface. Amicrocontroller1700 provides conversion of the data from theinput device1600 and controls interfacing of thekeyboard1610 andinput device1600 with thePC302. Themicrocontroller1700 has contained therein amemory1702 or it can have external memory. There are provided a plurality ofinput device interfaces1704 to theinput device1600, a plurality ofPC interfaces1706 to thePC302, and plurality ofkeyboard interfaces1708 to thekeyboard1610. In general, theinput device interfaces1704 comprise a serial data line, a ground line, and a power line. Similarly, thekeyboard interfaces1708 comprise a serial data line, a ground line, a clock line, and a power line. ThePC302 provides a clock line, a power line, a serial data, and a ground line for input to themicrocontroller1700. Themicrocontroller1700 is operable to receive signals from thekeyboard1610 and transfer the signals to thePC302 as keyboard signals. Operation with thekeyboard1610 is essentially a “pass-through” procedure. Data output from thekeyboard1610 is already in keyboard format, and therefore requires no conversion by thewedge interface1608. With respect to theinput device1600, the serial data is not compatible with akeyboard1610 and, therefore, it must be converted into a keyboard format in order to allow input thereof to the keyboard input of thePC302.

Themicrocontroller1700 performs this function after decoding this bar code information, and conversion of this bar code information into an appropriate stream of data which is comprised of the bar code information and the appended URL. This appended URL will be pre-stored in thememory1702 and is programmable at the time of manufacture. It is noted that thememory1702 is illustrated as being contained within themicrocontroller1702 to provide a single chip solution. However, this could be external memory that is accessible by themicrocontroller1702. Therefore, themicrocontroller1700 provides an interface between theinput device1600 and thekeyboard1610 to thePC302 which allows theinput device1600 to receive coded information and convert it to keyboard strokes or, alternatively, to merely pass-through the keystrokes from thekeyboard1610. Therefore, the user need not install any type of plug-in circuit board into the motherboard of thePC302 in order to provide an interface to theinput device1600; rather, the user need only utilize the already available keyboard port in order to input the appropriate data into the system.

In this particular disclosed embodiment, themicrocontroller1700 comprises a PIC16C73 microcontroller by Microchip Technologies™. The PIC16C73 device is a low cost CMOS 8-bit microcontroller with an integrated analog-to-digital converter. The PIC16C73 device, as illustrated in the disclosed embodiment, has 192 bytes of RAM and 4k×4 of EPROM memory. Themicrocontroller1700 can accommodate asynchronous or synchronous inputs from input devices connected to it. In this disclosed embodiment, communication to thekeyboard1610 is synchronous while it is asynchronous when communicating withinput device1600.

It should be noted that, although in this particular embodiment bar code information of thebar code1606 is input into the keyboard input port of thePC302, disclosed methods may also be advantageously utilized with high speed port architectures such as Universal Serial Bus (“USB”) and IEEE 1394.

Bar codes are structured to be read in either direction. Timing considerations need to be addressed because of the variety of individuals scanning the bar code introduce a wide variety of scan rates. Bar codes use bars of varying widths. The presence of a black bar generates a positive pulse, and the absence of a black bar generates no pulse. Each character of a conventional bar code has associated therewith seven pulses or bars. Depending on the width of the bars, the time between pulses varies. In this disclosed embodiment, theinterface circuitry1608 performs a “running” calculation of the scan time based upon the rising edge of the pulses commencing with the leader or header information. The minimum and maximum scans times are calculated continuously in software with theinterface1608 during the scanning process to ensure a successful scan by the user.

Referring now toFIG. 18, there is illustrated a sample message packet transmitted from the user'sPC302 to theARS308. Themessage packet1800 comprises a number of bits of information including thebar code information1802 obtained from the user scanning thebar code1606 with theinput device1600; theinput device ID1804 which is embedded in a memory in theinput device1600 and identifies it with a particular input device distributor; and auser ID1806 which is derived from the software running on thePC302 and which identifies uniquely with the user location. Note that the message packet includes other necessary information for the proper transmission for point to point.

Referring now toFIG. 19, there is illustrated a more detailed block diagram of the routing of the message packets in order to present the framed information to the user. As is mentioned hereinabove, when the user scans abar code1606 using theinput device1600, a input device program running on theuser PC302 is operable to interpret the information output by theinput device1600 and generate a message packet for transmission over theGCN306. The input device program assembles the message packet such that it is directed to theARS308 disposed on theGCN306. The message packet contains several pieces of information including theinput device ID1804 which links it to the input device distributor, theuser ID1806 which identifies the particular user using theinput device1600, andbar code information1802 describing a particular product of interest to the user. This message from thePC302 is transmitted over apath1900 to theARS308 where theARS database310 is accessed to cross reference theID information1804 andbar code information1802 to a particular advertiser and input device distributor. TheARS308 returns a message packet over apath1902 to theuser PC302 which contains routing information as to the location of various other sites disposed on theGCN306, for example, theadvertiser server312 and inputdevice distributor site1616.

It can be appreciated that other information can also be provided by theARS308 which more closely targets the particular user of theinput device1600. For example, if it is known that aparticular input device1600 is sold in a certain geographic area, this information can be useful in targeting the particular user with certain advertising information relevant to that geographic area. In any case, the information returned from theARS308 overpath1902 provides enough information for the input device program running on theuser PC302 to identify a number of other sites disposed on theGCN306. Theuser PC302 then processes the return message packet and routes another message packet over apath1904 to theadvertiser server312. Theadvertiser server312 then returns product information of the particular product in which the user was interested back to theuser PC302 over apath1906. Similarly, theuser PC302 routes information (e.g., the URL of the input device distributor site and the user profile) to the inputdevice distributor site1616 over apath1908 in order to obtain information back over apath1910 for framing any banners which identify the input device distributor. Additionally, theuser PC302 forwards a message packet to theE-commerce site1618 over apath1912 in order to return information regarding any particular advertisements the input device distributor wants to display to the user. The advertisements are returned to thePC302 over apath1914.

Referring now toFIG. 20, there is illustrated a block diagram of a browser window according to the disclosed embodiment. The browser window200 partitioned into a plurality of areas for framing specific information. Abar code area2002 displays that product information which the user was interested, an input device-specific area2004 displays information about the input device distributor; and anE-commerce area2006 displays advertising information that the input device distributor selects for display according to this particular user andinput device1600. As mentioned hereinabove, a program operable to process scanned bar code information with theunique input device1600 develops the browser window by partitioning it into specific areas for the framing of information. Therefore, information returned from theE-commerce site1608 is passed through theGCN306 to theparticular E-commerce frame2006. Similarly, information about the particular product of interest is returned from theadvertiser site312 across theGCN306 to the particular bar codespecific area2002. Information placed in the input, devicespecific area2004 is information about the input device distributor which is returned from the inputdevice distributor site1616 acrossGCN306.

Referring now toFIG. 21, there is illustrated a structure of information contained in the ARS database. TheARS database310 contains a variety of information required to properly interrogate and assemble packets for obtaining information from the various sites disposed on theGCN306. TheARS database310 has adatabase structure2100 which contains addresses for the web sites containing the product information requested by the user when scanning thebar code1606 with theinput device1600. Under a PRODUCT heading2102 are listed the particular bar codes and associated routing information for addressing the respective server location. For example, theARS server308 may contain any number of advertisers having unique URL addresses associated therewith. Therefore, thebar code1606 of a particular product is associated with a unique URL address which routes any request for information of that product to that particular advertiser's site. Also part of theARS database structure2000 is a heading of INPUT DEVICE under which is theinput device ID1804 and the distributor associated with thatinput device ID1804.

It can be appreciated that there may be a number of distributors using the disclosed architecture such that each distributor has an ID embedded in theinput device1600 which uniquely identifies that input device with the particular distributor. Therefore, the uniqueinput device ID1804 needs to be listed with the respective distributors of thatinput device1600 in order to process the information that needs to be framed and displayed to that particular user. Another heading under theARS database structure2100 is a user heading2106 which contains profile information associated with thatparticular user ID1806. As mentioned hereinabove, theuser ID1806 is obtained via the input device software running oh thePC302 and upon installation or subsequent configuration may request that the user input certain profile information which may be used to target that particular user with products and services which identify with that user profile. TheARS database structure2100 also contains an E-commerce heading2108 which contains information related to thebar code1606 and an advertisement that may be triggered by the request for that information. For example, anybar code1606 associated with apaper source1602 can be associated with the specific information in theARS database310. A user wishing to obtain information about a specific soft drink may, in fact, trigger an advertising response of a competitor product. Similarly, the user interested in information about that particular soft drink may also trigger information which is relevant to that particular product or a product which may normally be served in conjunction with that soft drink. Furthermore, if the user profile indicates that this individual has significant interest in finance or insurance, the request for information regarding this particular bar coded product may trigger advertisement from anE-commerce server1618 related to information about finance and insurance. It should be noted that the information described as contained within theARS database structure2100 is not limited to what has been described, but may comprise any number of pieces of information used to present desired information to the computer display of the user.

Referring now toFIG. 22, there is illustrated a flowchart of the process of receiving information from the user's perspective, and according to the disclosed embodiment. The input device software running on the user'sPC302 runs in the background until activated by output from theinput device1600. Therefore, flow moves to adecision block2200 where if a scanned input does not occur, flow moves out the “N” path and loops back to the input ofdecision block2200. On the other hand, if scanned input information is received, flow moves out the “Y” path to afunction block2202 where the input device software assembles a message packet containing the bar code information, theinput device ID1804 and theARS308 URL address. Additionally, the browser is launched in which this information is placed for transmission to theARS308. Flow then moves to afunction block2204 where the browser is partitioned into any number of areas which information is displayed when obtained from the inputdevice distributor site1616, theE-commerce site1618, and theadvertiser server312. It should be known that although three frames are shown in theparticular window2000 of this embodiment, the number of frames displayed in thewindow2000 is limited only by the available real estate of thewindow2000 area itself.

After the input device software partitions the browser window into one or more frames in preparation of receipt of return information, flow moves to adecision block2206 where the computer waits for information to be returned from the various sites disposed on theGCN306. If information is not returned, flow moves out the “N” path and simply loops back to the input to continue monitoring for receipt of the information. If information has been received, flow moves out the “Y” path to afunction block2208 where routing information for each frame (or partitioned area of the window2000) is inserted into one or more packets for transmission to the various sites. The various sites then return the requested information back to thePC302, as indicated infunction block2210. Flow is then to afunction block2212 where the proprietary software working in conjunction with the hosted browser places the returned information into the respective frames of the window. The user, viewing the display atPC302, then perceives a variety of information, one of which is the particular product information which he or she requested, in addition to input device distributor information, and possibly other advertisements based upon the user's profile.

Referring now toFIG. 23, there is illustrated a flowchart of the process according to the ARS. TheARS308 is operable to decode and process messages received from theGCN306. Therefore, flow is to adecision block2300 where, if bar code information is not received, flow is out the “N” path with loop-back to its input. If bar code information has been received, flow is to afunction block2302 where a matching process occurs to link the bar-coded product information to its respective manufacturer. TheARS database310 also associates the URL address of the manufacturer's server. When a match is found, theARS308 begins to assemble a message packet of information for transmission back to thePC302, as indicated infunction block2304. The message packet contains the product information and the URL address of the manufacturer's website. Flow then moves to adecision block2306 where theinput device ID1804 is compared with the list of input device IDs issued by the particular input device distributor. If theinput device ID1804 is validated, flow moves out the “Y” path to afunction block2308 where the message packet is appended with theinput device ID1804 and distributor routing address. Flow then moves to adecision block2310 where theARS308 determines if any E-commerce information is to be associated with a particularinput device ID1804. If so, flow is out the “Y” path to afunction block2312 where the message packet is appended with the E-commerce routing string. The E-commerce routing string provides addressing for theE-commerce server1618. Flow then moves to afunction block2314 where all message packets are returned back to thePC302 for processing.

Referring back todecision block2306, if theinput device ID1804 is determined to be invalid, flow moves out the “N” path and jumps forward to the input ofdecision block2314, since the lack of ainput device ID1804 interrupts the link to any advertising provided by theE-commerce server1618. At this point, the only information provided is the link to theadvertiser server312 for return of product information. Referring now todecision block2310, if no E-commerce information is available, flow moves out the “N” path and jumps forward to the input offunction block2314 where the message packet back to thePC302 contains only the URL of theadvertiser server312, the bar code information, the distributor-server1616 address andinput device ID1804 information.

Referring now toFIG. 24, there is illustrated a flowchart of the process performed at the E-commerce site. TheE-commerce server1618 receives the message packet from theuser PC302, as indicated infunction block2400, and decodes the packet to perform a match with the bar coded information. Moving on to adecision block2402, if the match is unsuccessful, flow is out the “N” path to afunction block2404 where the match is rejected. A message may be returned to indicate that a problem occurred and the user may need to re-scan theproduct bar code1606. If a successful match occurs, flow moves out the “Y” path to afunction block2406 where theinput device ID1804 is matched with the bar code product information. The bar coded information may be distributed to customers over a large geographic area. However, theinput device1606 may be coded for certain geographic areas. For example, ainput device1600 having an XXX ID may be restricted for sale in the Southwestern United States while ainput device1600 having a YYY ID may be sold only in the Northeast. In this way, geographic areas may be targeted with advertising more appealing to that particular area. Advertising returned to theuser PC302 may be focused further by obtaining a user profile when the software orinput device1600 are installed. In this way, advertising may be focused based upon the user profile. Therefore, flow moves to afunction block2408 to lookup the E-commerce action based upon theinput device ID1804 and the bar code information. Flow moves to afunction block2410 to assemble all the information into a packet for return to theuser PC302. The product information and/or user profile information may be returned. Flow is then to afunction block2412 where the message packet is transmitted.

Although it has heretofore been typical for users accessing computer networks such as the Internet to use personal computers (PCS) having a hard-wired network connection, an ever increasing number of users are connecting with various types of wireless devices. Such wireless devices include handheld computers (also known as personal digital assistants (“PDAs”)) having integrated wireless Internet access, e.g., the Palm VIIx produced by Palm Inc., cellular telephones having integrated Internet access capabilities, e.g., telephones conforming to the Wireless Application Protocol (WAP) established by the Wireless Application Protocol Forum Ltd., two-way digital pagers and other commercially available devices. All of these wireless devices includes a processor and a transmitter/receiver for sending and receiving radio frequency (RF) signals to provide two-way digital communication between the device's processor and a computer network. Of course, numerous additional components, e.g., memories, displays and input devices, are present in these wireless devices, their specific nature depending upon the type of device and desired features. The general construction of such wireless devices is, however, conventional and thus will not be described in detail.

Referring now toFIG. 25, there is illustrated a diagrammatic view of one embodiment of a system for connecting a wireless device to a remote location on a computer network. The system includes abeacon unit2502 disposed at ageographic location2504 and transmitting a beacon signal (denoted by arrow2506) into a target region adjacent to the beacon location. The system also includes a beacon signal receiver circuit (hereafter “BSRC”)2508 disposed with awireless device2510 and operably connected to the processor of the wireless device. Upon receiving thebeacon signal2506, theBSRC2508 sends control signals to the processor of thewireless device2510. The processor of thewireless device2510, in response to receiving these control signals, instructs the wireless device to connect to a specific remote location on a computer network. This connection can be completely automatic or it can be made at the option of the user, but in any case it obviates the need for the user to manually input a network address for the remote location.

In the embodiment illustrated, thebeacon unit2502 is mounted on an outdoor advertising structure (i.e., a billboard)2522 located adjacent to aroadway2514. Thewireless device2510 is disposed within anautomobile2512 traveling along theroadway2514. As previously described, the wireless-device2510 includes a processor and a transmitter/receiver for sending and receiving RF signals (denoted by arrows2516). The RF signals2516 provide two-way digital communications with a computer network, in thiscase GCN306, which may be the Internet. The RF signals2516 allow communication between the processor of thewireless device2510 and thecomputer network306 through awireless network interface2518, which in this case also serves as an Internet service provider (ISP). For purposes of illustration, thenetwork interface2518 inFIG. 25 shows only oneantenna2520; however, it will be appreciated that the typical wireless network interface comprises a plurality ofantennas2520 and associated radio equipment (not shown) which are distributed across the service area (e.g., in cells) and operably interconnected allowing thewireless device2510 to maintain virtually unbroken communications with thenetwork306 as it moves within the service area. It is noted that these wireless devices operate on a delay, such that a request for information may be buffered at thewireless device2510 in the event of a communication interruption. When communications are resumed, then the request is sent. In the same way, reply information is buffered, such that there may be a delay in returning the information. This is easily facilitated at theISP2518, due to the nature of the packet nature of the information transferred. For example, a packet of request information may be buffered at thewireless device2510 until communication is resumed, and then transmitted to theISP2518. Upon receipt, theISP2518 acknowledges to thewireless device2510 that the information has been received. TheISP2518 then handles the request outside of the wireless connection overlink2520. When connection is established with theadvertiser server312 and information retrieved, this information is buffered at theISP2518 and delivered to thewireless device2510 when communications permit. Since the primary communication protocol is packet-based in nature, this type of buffering is easily facilitated.

Referring now toFIG. 26, there is illustrated a diagrammatic view of thebeacon unit2502 of this embodiment. Thebeacon unit2502 includes atransmitter2602, amodulator2604 operably connected to the transmitter, and aprocessor2606 which is operably connected to the modulator. Thetransmitter2602 transmits thebeacon signal2506 into the target region. The information content (i.e., modulation) of thebeacon signal2506 is supplied to thetransmitter2602 by themodulator unit2604, which in turn receives the content from theprocessor2606. Thebeacon signal2506 may be modulated to carry information content in either digital or analog form. In the illustrated embodiment, thetransmitter2602 is a radio frequency (RF) unit for transmitting anRF beacon signal2506. Anantenna2608 is operably connected to thetransmitter2602 to provide desired signal radiation strength and directional properties, thereby controlling the size and shape of the target region. Using anomnidirectional antenna2608 will result in a generally circular target region which surrounds the location of thebeacon unit2502. Using adirectional antenna2608 will result in a narrower, more focused target region, typically to one side of thebeacon unit2502. It will be appreciated that the frequency of theRF beacon signal2506 will be different from the frequency used by thewireless device2510 fornetwork communication signals2516, thereby allowing the signals to operate simultaneously without causing interference.

While the illustrated embodiment uses anRF transmitter2602 for producing anRF beacon signal2506, it will be readily apparent that other types of transmitters may be used in alternative embodiments to produce beacon signals having different characteristics. For example, the beacon unit may have an optical transmitter for transmitting an optical beacon signal. Anoptical beacon signal2506 may have a carrier wavelength in the visible light portion, the infrared (IR) portion, or the ultraviolet (UV) portion of the electromagnetic spectrum. Such optical beacon signals may be produced using either non-coherent or coherent (e.g., laser) light sources. Optical beacon signals2506 will typically require a line-of-sight path between thebeacon2502 and theBSRC2508, however, this may be desirable for certain applications. Further, it avoids RF interference and licensing problems. In yet other embodiments, thebeacon unit2502 may have an acoustic transmitter for transmitting an acoustic beacon signal. Theacoustic beacon signal2506 may have a carrier wavelength in the human-perceptible frequency range or within the ultrasonic frequency range. Acoustic beacon signals2506 will typically be of short range, but a line-of-sight path is not required.

In the embodiment shown inFIG. 26, anelectric memory device2610 is operably connected to theprocessor2606. This could be conventional DRAM, flash DRAM or SRAM. Magnetic storage could also be utilized. Thememory device2610 includes one or more memory locations which store data, also known as “codes,” that can be retrieved by theprocessor2606. Theprocessor2606 sends signals indicative of the retrieved codes to themodulator2604 for incorporated as a component of thebeacon signal2506 transmitted by thetransmitter2602.

In the illustrated embodiment, two memory locations are provided in thememory device2610, afirst memory location2612 and asecond memory location2614. Each memory location contains a different code. For example, the first code (denoted “MSG. CODE”) in thefirst memory location2612 may be associated with a specific remote location on thenetwork306 to facilitate the connection of the wireless device receiving the code to that specific remote location. However, this association may have one of several forms. In one embodiment, thefirst code2612 actually includes routing information (e.g., a URL or other network address) associated with a specific remote location on the network. In other words, the routing information is actually “embedded” or “encoded” in thefirst code2612. In an alternative embodiment, thefirst code2612 does not actually include routing information to the remote location, but rather is associated with the remote location by other means. This may be by association of thefirst code2612 and the remote location in a secondary database such as theadvertiser server312 as further described below.

The second code (denoted in this example by “LOC. ID”) in thesecond memory location2614 is also transmitted by thetransmitter2602 as a component of thebeacon signal2506. The second code may be associated with an attribute of thebeacon unit2502. Examples of such attributes are the geographic location (i.e., LOC ID) of the beacon unit, a serial number of the beacon unit and/or a type descriptor characterizing the type of beacon unit. Each of these attributes can be used to facilitate the connection of thewireless device2510 receiving the code to the most appropriate specific remote location on thenetwork306. In some embodiments, the selection of remote location for connection of thewireless device2510 may be made by considering both thefirst code2612 and thesecond code2614. Thus, for example, if the first code “MSG CODE” was associated with a particular restaurant chain (e.g., “Burger X”), and the second code “LOC. ID” was associated with the geographic location of the beacon unit, then the invention could be used to connect thewireless device2510 to a remote location on thenetwork306 having information as to the geographic location of the nearest Burger X restaurant (relative to the beacon unit location). Alternately, where the selection of remote location is controlled only by the first code, then the second code can be used to collect information regarding the source of the connection, e.g., to determine the “ratings” (i.e., advertising effectiveness) of aparticular beacon unit2502.

It will be apparent that the association between the second code and the beacon unit attribute may have one of several forms, similar to those previously described for the first code. Thus, the second code may actually include the attribute, e.g., location, serial number or type descriptor, of the beacon unit embedded therewithin. Alternatively, the second code may be associated with the beacon unit attribute in a secondary database such as theARS308. Further, it will be apparent that some embodiments may include only one code, in which case the first code may be associated with any of the beacon unit attributes (e.g., location, serial number or type descriptor) as previously discussed.

An input/output (“I/O”)interface circuit2616 may be included in thebeacon unit2502 to allow thememory unit2610 to be reprogrammed with new codes. The I/O circuit2616 is operably connected between theprocessor2606 and anexternal instruction source2618. The I/O circuit2616 is thus operably connected to thememory unit2610. Specifically, the I/O circuit2616 receives instruction signals (denoted by reference number2620) from theexternal instruction source2618 and transforms them into system instruction signals (denoted by reference number2622) usable by theprocessor2606. In response to receipt of thesystem instruction signals2622, theprocessor2606 accesses thememory unit2610 and changes the codes in memory locations, e.g.,locations2612 and2614. In this way, thebeacon unit2502 can be updated to change the remote location to which it directs nearby wireless devices. It will be apparent that a variety of external instruction sources may be utilized. In the illustrated embodiment, theinstruction source2618 is a public switched telephone network (“PSTN”) connected to thebeacon unit2502 by telephone lines2524 (see FIG.25). In such a case, the I/O circuit2616 will include a telephone modem circuit allowing thebeacon unit2502 to be updated from a remote location. In another embodiment, theinstruction source2618 may be a keypad or keyboard attached directly to the I/O circuit2616. In this case, no telephone lines are required, however, service personnel would need to visit thebeacon unit2502 to update the programming. In yet another embodiment, theinstruction source2618 may be an RF receiver circuit, an optical receiver circuit, or an acoustic receiver circuit. In such cases, thebeacon unit2502 may be updated by transmitting instructions on RF, optical or acoustic signals having a frequency appropriate for the respective receiver circuit.

Referring now toFIG. 27, there is illustrated a diagrammatic view of the beacon signal receiver circuit (i.e., “BSRC”)2508 of this embodiment and the associatedwireless device2510. As previously described, theBSRC2508 is disposed with thewireless device2510. In the illustrated embodiment, theBSRC2508 has the form of an add-on module which is attached to the exterior shell2702 of thewireless device2510. The two devices pass electronic signals through an electrical interface comprising cooperatingelectrical connectors2704 and2706 located on theBSRC2508 andwireless device2510, respectively. In alternative embodiments, however, theBSRC2508 may be supplied as an integral part of thewireless device2510, and located entirely within its exterior shell2702. In such case, the interface between theBSRC2508 and thewireless device2510 would be an integral part of the overall device, and thediscrete connectors2704 and2706 would be unnecessary.

TheBSRC2508 includes areceiver unit2708 and aprocessor2710. Thereceiver unit2708 is adapted to receive thebeacon signal2506 transmitted by thebeacon unit2502. In the illustrated embodiment, thereceiver unit2708 is an RF receiver adapted to receive signals from theRF transmitter2602, and thus is provided with anantenna2712 to improve reception. In other embodiments, however, thereceiver unit2708 may be an optical receiver or an acoustic receiver to correspond to the type of transmitter used by thebeacon unit2502. In still other embodiments, theBSRC2508 may include multiple receiver units of different types (e.g. an RF unit and an optical unit) or operating at different wavelengths. Thebeacon signal2506 received by thereceiver unit2708 is then demodulated as necessary to extract the information content, e.g., the codes transmitted from thebeacon unit memories2612 and/or2614. Signals indicative of the received codes (or other information content) are then passed to theBSRC processor2710. In response to receiving the signals indicative of the received codes, theBSRC processor2710 sends control signals across theinterface2704,2706 to theprocessor2714 of thewireless device2510.

As previously discussed, thewireless device2510 includes aprocessor2714 operably connected to an RF transmitter/receiver unit2716. The RF transmitter/receiver unit2716 transmits and receives RF signals2516 to provide two-way communication between thewireless device2510 and thecomputer network306. Thewireless device2510 may further include various types of amemory unit2718, a keypad, keyboard, touch pad or otheruser input device2720, adisplay screen2722, and an audio input/output device2724 (e.g., speaker and/or microphone), depending on its exact type, i.e., whether it is a Internet-ready telephone, an Internet connected personal digital assistant or some other type of network wireless device. The control signals received by thewireless device processor2714 from theBSRC processor2710 cause thewireless device2510 to sendRF signals2516 to thecomputer network306 whereby the wireless device is connected to a specific remote location on the network. These RF signals2516 may include components indicative of the codes received from thememory2610 of thebeacon unit2502.

In the embodiment shown inFIG. 27, anelectronic memory device2726 is operably connected to theBSRC processor2710. The memory device2626 includes one or more memory locations which store data, i.e., “codes”, that can be retrieved by theBSRC processor2710. TheBSRC processor2710 can send signals indicative of the retrieved code to thewireless device processor2714, which in turn may incorporate the code as a component of theRF signal2516 used to connect thewireless device2510 to the remote site on thecomputer network306. Thus, the RF signals2516 transmitted by thewireless device2510 may include components indicative of codes, or portions thereof, received from thememory2610 of thebeacon unit2502 and/or components indicative of −10 codes received from thememory2726 of theBSRC2508.

In the illustrated embodiment, onememory location2728 is provided in the memory device2726 (denoted “SER. NO.”). In this embodiment, the code is associated with a serial number for theindividual BSRC2508. This is typically non-volatile memory. This serial number can be provided to the remote location to which thewireless device2510 is connected to allow tracking of inquiries or the collection of data regarding the effectiveness of the system. In another embodiment, the code may be associated with a type descriptor characterizing the type ofBSRC2508. This type descriptor, when transmitted to theadvertiser server312, may allow selection of a remote location on the network having content which is optimized for display on the particular type of BSRC being connected. In other embodiments, the code located in thememory location2728 may be associated with the address of a remote location on thenetwork306, for example the location of theadvertiser server312.

Once thewireless device2510 has received the codes from thebeacon unit2502 and theBSRC2508, the connection of the wireless device to a remote location on thecomputer network306 may be accomplished generally as described for previous embodiments receiving codes from external devices, e.g., from bar code readers, audio tones embedded in broadcasts or recorded media. For example, as illustrated inFIG. 25, a first computer, e.g., theARS308, is disposed on thecomputer network306. A computer database, e.g., theadvertiser database310, is operably connected to thefirst computer308. Thecomputer database310 includes a plurality of routing information for remote locations on the computer network and a plurality of first codes (i.e., corresponding to the codes from the beacon unit memory2612) and associating each of the routing information with at least one of the first codes. Upon receiving a message packet (i.e., a signal containing information components which are indicative of the first code) transmitted from thewireless device2510 across thenetwork306, thefirst computer308 accesses thecomputer database310, retrieves the routing information associated with the particular first code, and transmits the routing information associated with the particular first code across the computer network back to the wireless device. It will be readily apparent that, in some embodiments the routing information in thedatabase310 may be further associated with a plurality of additional codes (e.g., second code frombeacon unit memory2614 and third code from BSRC memory2728) to allow for further refining of the selection of routing information to be transmitted back to thewireless device2510.

In response to receiving the routing information associated with the particular first code (and any additional codes, if applicable, as described above) from thefirst computer308, thewireless device2510 then sends a second message packet across the network to a remote location as directed by the routing information just received. This may be the desired remote location, or alternatively, codes incorporated into the second message packet may be evaluated to select a particular remote location from among a plurality of locations accessible through this site. Once the determination has been made, thewireless device2510 is connected to the desired remote site on thenetwork306. In most cases, information content will be returned from the remote site to the wireless device for further evaluation or display to the user.

Referring now toFIGS. 28a-28d, there is illustrated a flowchart of the process for connecting a wireless device to a remote location on a computer network in accordance with another aspect of the invention. The process begins in the “START” block2802 (FIG. 28a) and then proceeds to functionblock2804, wherein thebeacon unit processor2606 retrieves the code or codes from thebeacon unit memory2610. In the illustrated embodiment, a first and second code are retrieved from the beacon unit memory. The process then proceeds to function block2806, wherein thebeacon unit2502 transmits as a continual and/or repetitive broadcast into the target zone thebeacon signal2506 which incorporates information indicative of the first code and the second code. The process then proceeds to function block2808, wherein theBSRC2508 which is within the target zone receives thebeacon signal2506 and extracts the first and second codes. If theBSRC2508 includes a memory unit2726 (this test being represented by the decision block2809), the process then proceeds to functionblock2810 where theBSRC processor2710 retrieves the code or codes from the BSRC memory. If theBSRC2508 does not include a memory unit, then functionblock2810 is omitted. The process then proceeds to function block2812 (FIG. 28b), wherein theBSRC processor2710 passes the first, second, and/or third codes (as applicable) to theprocessor2714 of thewireless device2510 for buffering therein.

Once thewireless device2510 receives the signals indicative of codes from theBSRC2508, the process then proceeds to functionblock2814, wherein the wireless device sends RF signals2516 having a first message packet which incorporates the codes via theISP2518 to a first location on thenetwork306. In some embodiments, e.g., where the codes from thebeacon unit2502 actually include embedded routing information to the desired remote location, e.g., location2526 (FIG.25), the first message packet may be routed directly to the desired remote location on thenetwork306 using the routing information from the code. In the illustrated embodiment, however, the codes in the RF signals2516 do not contain embedded routing information relating to the desired remote location. Therefore, it is necessary for the first message packet to be routed to a known intermediate site, e.g.,ARS308, where the codes can be used to retrieve the necessary routing information from a database, e.g.,database310. In such case, the RF signals2516 will incorporate default routing information necessary to guide the first message packet to the intermediate location. It will be understood however, that this fixed routing information, i.e., to an intermediate location used to obtain further routing information to remote sites, is to be distinguished from the routing information to the desired remote location. The process next proceeds to functionblock2816, wherein theintermediate server308 receives the message packet including the codes received from thebeacon unit2502 and/orBSRC2508 and extracts the codes. The process then proceeds to functionblock2818, wherein theintermediate server308 accesses thecomputer database310 and retrieves the routing information associated with the codes.

After retrieving the routing information associated with the codes received from thebeacon unit2502 and/orBSRC2508 from thecomputer database310, the process continues to functionblock2820, wherein theintermediate server308 sends another message packet including the routing information back across thenetwork306 to thewireless device2510. The process then proceeds to function block2822 (FIG. 28c), wherein thewireless device2510 sends a second message packet across thenetwork308 to a remote location using the routing information just retrieved from theintermediate site308. The second message packet may also include some or all of the codes received from thebeacon unit2502 and/orBSRC2508. The process then proceeds to functionblock2824, wherein the second message packet is received at the remote location specified by the routing information retrieved from theintermediate site308. As represented by thedecision block2826, in some embodiments, this remote location may be the desiredremote location2526, in which case the process proceeds to functionblock2828 and the connection of thewireless device2510 to a remote location on the network has been completed (as denoted in function block2830). In the illustrated embodiment, however, this location is a “portal” site, e.g.,advertiser server312, providing access to a plurality of additional remote locations on the network, e.g., content locations designated byreference numbers2526 and2528. In this latter case, the process proceeds fromdecision block2826 to functionblock2832. In thefunction block2832, the codes in the second message packet (which originated from thebeacon unit2502 and/or BSRC2508) are used to access a database or lookup table at theportal location312 associating each of the plurality of remote locations with one or more of the codes. This process then also proceeds to functionblock2830, wherein the associated one of the plurality of remote locations, i.e., the desiredlocation2526, is connected to the wireless device to complete the basic process.

In the illustrated embodiment, the process is extended beyond the basic process to anadditional function block2832, wherein information content form theremote site2526 is sent back across thenetwork306 to thewireless device2510. The extended process next proceeds to functionblock2834, wherein content from the desired remote location is received by the wireless-device2510. The extended process then proceeds to functionblock2836, wherein the received content is further processed or displayed by thewireless device2510 to the user. The extended process then proceeds to the “END”block2832 indicating that the extended process is complete.

Referring now toFIG. 29, there is illustrated an aerial view (i.e., plan view) of ageographic region2900 in which an embodiment of the system has been deployed. Thegeographic region2900 includes afirst roadway2514, asecond roadway2902, anintersection2904 between the two, and aretail establishment2906 disposed alongside the second roadway. In this embodiment, three beacon units denoted byreference numerals2502a,2502band2502c, respectively, are positioned along thefirst roadway2514. The beacon units may be mounted on antenna towers, billboards, buildings or even smaller structures such as park benches, depending upon the type of beacon and coverage range required. In this example, each of thebeacon units2502a,2502band2502ctransmits anRF beacon signal2506 using anomnidirectional antenna2604, resulting incircular target regions2910a,2910band2910c, respectively. In this embodiment, thebeacon units2502a,2502band2502care spaced apart a distance D1 which is greater than the sum of the radii for adjacent target regions, thus, thetarget regions2910a,2910band2910cform “cells” which do not overlap. This arrangement allows adjacent beacon units to broadcast beacon signals on the same frequency without interfering with one another, and it also allows theBSRC2508 to utilize a single reception frequency. It will be apparent, however, that other embodiments of the invention may employ beacon units transmitting on different and/or multiple frequencies and beacon signal receiver units receiving on different and/or multiple frequencies.

Referring still toFIG. 29, as theautomobile2512 travels along thefirst roadway2514 in the direction indicated byarrow2912, it passes sequentially through thetarget regions2910aand2910b(as indicted by phantom lines) to its current position in target region2910c. ABSRC2508 operably connected to awireless device2510 in theautomobile2512 will therefore sequentially receive beacon signals from each of thebeacon units2502a,2502band2502c. As previously described, thewireless device2510 may be connected to a remote site on the network upon receiving each of the beacon signals. For example, thefirst beacon unit2502amay cause thewireless device2510 to connect to a remote location providing geographically relevant information regarding the nearbyretail establishment2906 and indicating that it can be reached by turning at an upcoming intersection. Thethird beacon unit2502c, whose target area2910ccovers theintersection2904, may cause thewireless device2510 to connect to a remote location also providing geographically relevant information, i.e., that the driver should turn ontoroadway2902 at the current intersection (i.e., intersection2904) to reachestablishment2906. On the other hand, thesecond beacon unit2502b, may cause thewireless device2510 to connect to a remote location which provides information having no geographical relevance, e.g., information relating to the product advertised on an adjacent billboard.

It will be appreciated that, while all the previously described embodiments utilize abeacon unit2502 having a fixed geographic location, this is not a requirement of the invention. In other embodiments, thebeacon unit2502 may be mounted on a vehicle, e.g., a bus, a taxi, a truck, a train, an automobile, or even an aircraft, and equipped with a mobile power supply so that it may transmit thebeacon signal2506 as the vehicle moves. The target area of the beacon signal transmission thus moves as the vehicle moves, encompassing various wireless devices whether they are moving or stationary. Those wireless devices equipped with acompatible BSRC2508 may then be automatically connected to a remote location on a network as previously described.

Although the preferred embodiment has been described in detail, it should be understood that various changes, substitutions and alterations can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
